Ok just completed my test on the scope.Quote:

So is the green wire the relay and the blue the mute? They both turn "on" and "off" at the same time?
A nice-to-have would be an output that activates based on actual jamming instead of the duration of the alert. Maybe a setting in a future firmware update.
Does the LED indicate when jamming starts and stops? Like on the LI, where the LED flashes during jamming and steady when not, even when the audio alert is still playing.
Inquiring minds of jammer auto-kill developers want to know. ;)

We will have to ask about that in a future update.
'' The BLUE wire is GROUND triggered and will ground when the alert begins and will stay grounded until the alert completes. ''
Question :
During an attack , if one of the button is pressed (thus returning to park status) does the ground
is cut off ? This a small detail i cannot test at the moment .
I plan to use this wire for a brake light kill relay.
I know that on the Li , the ground stays triggered even when the switch is set to detect only.
Thanks.
Do the wires trigger when the parking mode senses an object also or only when in the defense mode (jamming)?
The ground stays triggered as long as it is receiving a signal and then stops approximately 5 seconds after the head has received it's last pulse. (ie I stopped the gun and 5 seconds later it goes back to non-grounded / 0v depending on which wire you are using)Quote:

Nice to know about the LED in Pro mode. I assume the auxiliary LED does this as well as the one in the control unit?
That sounds like the way to interface an ALP my auto-kill. I already have an LI compatible LED sense input, and a mute sense input. By using both, it can determine when jamming starts and stops, without falsely triggering due to parking mode signals, etc.
^ First of all... you're imaging things... :highly_amused: seriously though yes the LED works the same as the control unit. It's for a stealth install when you don't want the control module visible.
Updates : triggering a relay under an alert with the Green\Blue wires .
Got an email from the support ALP :
'' sorry, relays are not yet supported. We constantly work on new updates and functionality extensions, as you probably are aware of. Stay tuned for our newsletters, latest news are usually updated monthly.
Have a great day!
Your ALPriority Support team ''.
I tested with amperemeter : green\blue pushed 45milliwatts.
The smallest relay i tested , 3.5 volts coil , cannot be triggered ,
it draws 50 milliwatts.
I ordered a SSR solid state relay , 3 to 32 volts coil , i will test and report ,
it could work since it is supposed to use very little amperage.
Under alert , the polarity of green\blue is reversed , it is different from the Li which connects to ground
under alert \black wire\ .
Update :
i recieved the SSR , solid state relay , rated to trigger from 3 to 32 volts .
Verdict : not enough juice to trigger.
One thing i realise with those SSR : with proper voltage it triggers only AC apparatus !
You'll need to use a transistor to drive the relay.
A circuit like this will work on the green (5v) wire. Use a relay with a 12V coil.

I've bought 2 of these, which should hopefully work on the +5V green wire ;

Have yet to test it yet :)
That looks like it will work. The issue is the ALP is sending I believe standard TTL I/O. (+5v). Which is just not enough to drive a relay. Using that device will allow you to drive a relay based on the Vcc on the board triggering when the ALP goes high. Let us know how you make out.
From the pdf specification , at 3 volts , it pulls 60ma , i hope it works though as i tested the outputQuote:

Which voltage did you order ?
Morale : please Al team , implement an easy way to trigger a 12 volts relay ....would make our life easier ,
thouh it is already in their plans :courage:
Yes, although at 12V supply voltage (the ones I ordered as I will be switching a small 12Vdc load), its quoted as < 45mA 'on'
What are you up to WB? Post in the secure Aussie section if its what I think you are doing...

I see , just to let you know my experience :Quote:

Thanks Tman - will let you know :)
This is also quoted in the ebay text ;
Quote:
Control signal voltage: Data level (3.3v) or TTL (5v) Range is 1-12v DC - takes less than 20mA from logic source.
At 20ma ....i think you got the solution !
http://www.ebay.com.au/itm/Mini-1-Ch...item461ad3e7fa
I found this cheapy , is it working on the same principle ? they say TTL source for the signal , i guess it needs
another source (5volts) to trigger the relay ....not very familiar with Arduino system.

It has two Vccs because of the isolation circuit (opto-coupler). For your application they can be connected together. The Ctrl input would go to the relay wire on the ALP, and Vcc would go to a 5V supply (you may have to use a 7805 or 78L05 regulator or something). If you're using an Arduino it would have a 5V supply on-board.Quote:

Ok, just did a quick test of the relay - looks like we're in luck :)Quote:

The green LED on the relay comes on during alert, and you can hear the click of the relay activating. It remains activated all the time the alert is being played
Instructions say when relay activates, Normally Open (NO) is connected with COM (there is also Normally Closed (NC)) - confirmed with continuity check on multimeter.
Great job now just remember whatever you connect is going to stay on during the entire alert as I stated in the op.Quote:
